Regarding x ray collimator, do you know the fully automatic working principle of led? The fully automatic working principle of led and electric working principle of led have little difference in structure. The difference is that the fully automatic working principle of led has a condition monitoring device with lead leaf inside. Functionally with the adaptation of the focal length, the fully automatic working principle of led has the ability to automatically report the size of its field, mostly for perspective.
In the fluoroscopy, in order to prevent the patient from receiving unnecessary radiation, to prevent excessive X-rays from shining outside the screen, or to affect the enhancer, the working principle of led is limited in the circuit to make the working principle of led In the maximum open position, the illumination field coincides with the diameter of the input screen of the influence enhancer, and with the adaptation of the focal length, the size of the illumination field can be tracked and controlled, so that the illumination field never exceeds the focal length. Enter the edge of the screen.
If spot photography is to be performed in perspective, the X-ray machine sends a corresponding control signal to the control center of the working principle of the control center. At the time of spot photography preparation, the illumination field is switched from the perspective state to the gasket photography state, and the size of the illumination field is consistent with the film and the division method required.
